ทดลอง ล่าสุด ไม่ได้ ยังไม่รู้สาเหตุ
Code ของ Curl
curl -i -d "{\"url\": \"http://abc.com/x.jpg\"}" -H "Content-Type: application/json" -H "Prediction-Key: 1212324234123412341234" -X POST https://southcentralus.api.cognitive.microsoft.com/customvision/v3.0/Prediction/xxxx-aaaa-bbb-ccc/classify/iterations/Iteration3/url?application=CHK_ABC
Code ของ Python 3.8 ต้องลง rest ก่อน python -m pip install rest
import requests
headers = {
'Content-Type': 'application/json',
'Prediction-Key': 'key',
}
params = (
('application', 'CHK_ABC'),
)
data = '{"url": "http://abc.com/x.jpg"}'
response = requests.post('https://southcentralus.api.cognitive.microsoft.com/customvision/v3.0/Prediction/prjectid-xxxx/classify/iterations/Iteration3/url', headers=headers, params=params, data=data)
print(response.text)
